EVOTOMYS 251 



(3) E. irl-Hfeiisis Ognev. " Fur long and bushy, the hairs in 

 suninior coat attaining a length of 15-2 mm. Mantle rusty- 

 brownish, narrow, the dirty buffy grey of the flanks extending 

 far up dorsally ; fore-part of head and cheeks grey yellowish-buff. 

 Under surface dirty white with an evident huffish tint. Hind-foot 

 with six jiads. Skull smaller than that of E. iissiirioisis ; coronal 

 suture ])ressed a little backwards. Cheek-teeth with the com- 

 paratively narrow enamel loops lengthened ; posterior loop of m^ 

 visibly stretched." 



Measiirements. — Head and body 88-2-1 17-8 mm.; tail 

 28-1 (subad.)-42-7; hind-foot (" w. claws") 16-7-18-6; ear 12-7 

 (subad.)-15-7. Skull: total length 25-5-26-5; condylo-basal 

 (probably condylo-basilar) length 24-25-5 ; greatest breadth of 

 cranium 12-7-12-9 ; zygomatic breadth 13-2 (subad.) — -14-6- 

 14-8 (ad.); height of " basioccipital region" 7-2-7-4; length of 

 nasals 7-5-8-2; upper molars 6-1-6-3. 



Neither in this account nor in the figures of the skull and teeth 

 })ublished by Ognev can I find any reason for distinguishing 

 ■■ l)-ki(tcii.sis " from E. r. mfocaims. In addition Mr. Montagu has 

 kindly examined Ognev's type in Leningrad for me, and he tells 

 me that he could not distinguish it from E. rvfocwnis ; he found 

 the condylo-basal length of the oldest skull to be 26-4 mm., so 

 that by " condylo-basal length " Ognev probably means the 

 shorter " condylo-basilar " measurement. 



In an account of the voles obtained by the second and third 

 Asiatic expeditions of the American Museum, Mr. G. M. Allen ^ 

 says : — ■" A good series [of E. rufocanus] was secured along the 

 southern border of the forest at stations fifteen miles north and 

 forty-five miles north-east of Urga, Mongolia, as well as at Sain 

 Noin Khan to the westward. It seems to occur, therefore, in the 

 same general localities as the smaller red-backed mouse [E. rutilus]. 

 I have carefully com})ared this series with topotypes of rufocanus 

 from Sweden and can find no tangible differences."
